Swap USDT from Solana to WETH on Arbitrum One
Swap USDT from Solana to WETH on Arbitrum One. Tether's SPL mint leaves Solana, and Arbitrum WETH is what can arrive. You do not receive the ETH that pays gas.
Spend Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB in Phantom. Solscan shows the mint. There is no ERC-20 approval. WETH is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 on chain id 42161, not Nova. Arbiscan is the check. The gas sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is ETH, which this route skips. Mainnet WETH is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2, chain id 1, about 12 second blocks, Etherscan. WBTC is not this token.
Inventory WETH still needs a fee balance
Do not recycle a mainnet address
SOL on the way out, ETH on the way in, WETH in the middle

Frequently asked questions
What is the best way to swap USDT from Solana to WETH on Arbitrum One?
Spend Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB in Phantom. Solscan shows the mint. XAUConnect compares live routes and lets your own wallet sign.
Can this WETH pay Arbitrum One gas?
No. 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 cannot. ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, pays chain id 42161, not Nova. Tether's mint left Solana. Hold ETH and check Arbiscan. If fees were the only shortage, this route is the wrong page. Keep the destination gas token or the arrival cannot move. The quote minimum is the floor, and a thin floor is a reason to stop.
Is this Ethereum WETH?
No. Mainnet WETH is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 on chain id 1, Etherscan, about 12 second blocks. This route credits Arbitrum One only. Other networks use other wrapper addresses. If the pool is not on 42161, do not sell the Solana mint into this contract. A block interval is not a delivery time for the bridge.
Does Phantom show an approval for USDT?
No. Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB is an SPL mint. Solscan records the send. Keep native SOL for the fee. The WETH arrives in an EVM wallet that also needs ETH. There is nothing to revoke on Solana after the signature. Switch the wallet to the destination chain before you judge the balance.
